Modules

aggregator

Stats aggregator: receives StatsEvent from the runtime’s fan-out adapter and flushes counter deltas into per-skill stats.json sidecars.

capability

constraint

credit

Credit ledger data types (M7c).

evolution

Skill evolution log — records every generation of a skill.

gene

Skill gene model (M7b).

hash

inventory

lifecycle

Pure-function lifecycle + decay layer. Functions take inputs, return outputs, never touch disk. M5b’s sweep calls these to decide transitions and persist; M5a’s doctor calls them for read-only display.

loader

Single-pass skill loader: lists global + per-agent skills, resolves trust level, checks drift, returns one flat Vec.

local

Local skill store helpers — list installed, resolve, remove, search, trust.

lockfile

manifest

Skill manifest — full serde representation of canonical skill.yaml.

mcp

MCP capability declaration vocabulary (M6a).

parser

Dual-format parser. Canonical YAML is the source of truth; markdown frontmatter is the human-authoring surface that round-trips via canonical_from_markdown() / markdown_from_canonical().

peers

Peer agent enumeration (M7a).

registry

Git-based skill registry data model for index.yaml.

resolve

scan

Skill content security scanner — wires the four sub-scanners into a single scan_skill_content() entry point used by mur skill validate and by the install pipeline.

sign

stats

Per-skill runtime statistics. Not signed, not part of the publisher manifest. Lives at <MUR_HOME>/skills/<name>/stats.json and is rebuildable from the JSONL trace log via mur skill reindex-stats.

store

types

Skill type enums.

validate

Schema validation enforced after parsing.

version

Schema version anchor for skill manifests.
